Ionic Character of Metallic (Alkali Metals) Hydrides , and Reactivity

First and foremost, hydrides of alkali metals are ionic in nature. So, you cannot use Fajan's rule to determine ionic character as it is only used for covalent compounds. For ionic compounds we use ...

Why can't group 2B metals (Zn, Cd, Hg) form complexes with ligands such as CO, nitrosyl (NO), and olefins but do from complexes with NH3, CN- etc?

In addition to Oscar's zinc complex, I want to point out the very first thermally stable cadmium carbonyl complex, $\ce{[Cd(CO)3(C6H3Cl)]4ยท2H2O}$. It has been synthesized with an overall yield of 35%. ...

Why can't group 2B metals (Zn, Cd, Hg) form complexes with ligands such as CO, nitrosyl (NO), and olefins but do from complexes with NH3, CN- etc?

Zinc actually has been incorporated into a room-temperature carbonyl complex embeeded into a zeolite matrix [1]. Ordinarily, G12 metal centers have their $d$ orbitals too tightly bound to serve as pi ...

Where are the electrons located when two atomic orbitals overlap? (VBT)

Orbitals have fuzzy boundaries so the extent of their overlapping is a matter of taste in the first place. In the context of this linear combination approach electrons are free to use the whole ...

Why does boron have higher affinity for fluorine than oxygen?

The question might he better posed as "Why does fluorine have a greater affinity for just about everything (including boron) than oxygen? The answer is first off, technically fluorine does not ...

Why does boron have higher affinity for fluorine than oxygen?

There are competing effects of resonance and steric hindrance in $\ce{B(OH)3}$ and $\ce{BF3}$. It is the reduced steric hindrance, not resonance, that dominates stability in this case. Boron has small ...

What does the dot indicate in the molecular formula for white lead?

It could be as well written as $\ce{Pb3(OH)2(CO3)2}$. The formula $\ce{2 PbCO3 . Pb(OH)2}$ is used as better visualization of composition being an intermediate between lead carbonate and lead ...
